[Q] Trickle Charging w/ Stock Charger? - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Hi all;
I posted this in another thread but there was no reply there, maybe since it was the accessories forum the wrong people are looking at it? Anyway, this issue is different from the thread in which I replied, so I'll just make this it's own discussion.
Basically, my problem is that when I plug my Samsung Galaxy Tab 10.1 in to the wall with the out-of-the-box Samsung charger, the device charges at a rate of about 3-5% per hour. This is way slower than it was charging about a week ago, but one day, this started happening. A couple things to note are that the "battery" screen in settings shows the device is discharging even though it's plugged in. There is, however, no red "X" over the battery symbol. The cord for the charger is a bit frayed on the end that goes into the device, but this was not causing any issue before. Could the cord be the problem, or is this an issue with my device? Any suggestions, advice, and/or info are greatly appreciated!

UPDATE: I connected the tablet to the Samsung keyboard dock and it now charges without issue. Same cord, same block, but when connected to the dock, the battery screen shows it is "Charging (AC)" instead of "Discharging" and it charges way faster. This has me thinking it was a software issue...could rooting the device to wipe battery data be the most likely permanent solution?

[Q] SGS3 (Samsung Galaxy S3) Charge Issues

Is anybody having issues with the charging of their SGS3?
It seems that my device charges as and when it wants. I wanted to find out how wide spread the issue is and the different cases in which it does not charge.
This could possibly help find some sort of temporary resolution.
My Galaxy note is extremely temperamental when it comes to charging. It doesn't seem to like any other cable than the one that came with it. I've been through several cables trying to find another that will charge it.
Some cables said they were charging the unit (and it the meter was going up) until I unplugged the cable to find the battery level drop from 100% to 5% in a second. With another cable, the handset said it was being charged, but the screen locked out and wouldn't recognise gestures. Others just wouldn't charge and the phone didn't even recognise them. It was all very odd.
In the end I gave up and just used the stock cable. It could be a Samsung thing?!?

Same for me on SGS2 (GT-I9100). Often it discharged so much, it was switched off by the battery's low-voltage-protection-circuit. Then the phone started again because it had 5V at the USB and tried charging, but couldn't because the battery was not able to power the phone until the charging process started, so I had a nice bootloop
I had to build a constant-current-circuit with a LM317 to charge the battery a bit until it could be charged by the phone again.
It seems like the only way of getting rid of this is by using the original charger..
(Would be great if Samsung could make their devices be able to run from usb-power only)

Battery charging problem

Hi,
I'm owning a Samsung GT-I9000 Galaxy S3. Having it for about 3 months now.
Every night my phone's always charger. But I've had several times a strange problem that my phone charged only a little bit. Or even did not charge at all. I've seen a lot of problems on the internet of S3 users that are having battery issues, but on this particular problem I couldn't find an answer.
In the attachments two screenshots of the battery usage when I had this charging problem at night. Does anyone have any idea what I have to do next to avoid this problem? Already changed the charger from Samsung for an HTC, because i read that those Samsung adapters are really crappy. But not tried another cable. Could the cable be the problem?
Thanks in advance!

You have already worked out the next step, why not do it before asking? Hundreds of similar posts if you search.
If you are on a fully stock rom then the likely causes, in order are charger, lead, battery, charging IC inside phone. Try the first three then sent for repair.

Battery weird - seems to be phone but no obvious hardware issue

I have a galaxy s2 and bought a new battery recently (samsung one) thinking it would solve an issue which I thought was my battery.
Its very hard to describe but will do my best (have checked other threads but nothing quite like this..):
The battery will always say charging when plugged in but will sometimes increase in charge and other times not. I can charge overnight sometimes and it will say charging 7% and in the morning be completely dead and will not even show the charging animation (I have fixed by using my girlfreinds phone to charge it a bit and then it will be fine for a bit).
I thought might be charger - but my girlfreinds s2 charges fine on it - her phone works fine on both batteries and charges both fine.
Seems to be something to do with my hardware and I thought it may be the charging port - but not sure as it does still say charging without having to wiggle or anything like that so that suggests not the port.
The other thing that suggests something other than the port is I have had a battery in my girlfriends phone with it on, then plug it in and it said charging 37%, take it out and put in my phone with it plugged in and turn the phone on and it will say charging 4%...
Does anyone have any ideas as to this? Any things to try?
Thanks heaps in advance!
Do a clean install of stock & test for a day or two, if you're already running stock skip straight to replacing the USB board/port. Given you've already replaced your battery, this is likely to be the cause of the issue. Search for KeithRoss39's guide in the General section; it's quick/easy/cheap (<AUD$10 for me) to do.

[Q] Weird Charging Issue

Hello,
I have Galaxy S2 and having some charging issue. Yesterday, when I plugged it in the wall charger, it didn't get charged (i.e. even the flash on battery was not coming up) and when I tried to restart the phone, it powered off but didn't switch on. I tried holding the power button to turn it on but it didn't. So, I pulled out the battery and left the cell for some time like 20 mins or so. After re-inserting the battery, it turned on but still was not getting charged. I tried to change the USB cable as well but nothing helped. I then tried to charge it via my Laptop it actually started the charging process but with error on Laptop saying "USB Device not recognized".
Today, I tried the wall charger again and here's I found something: when my phone is ON and I plug it in the wall charger it doesn't charge but as soon as I turn the phone OFF, my phone starts getting charged (Battery image comes on screen which usually comes when the phone is off). So, that's how I am charging my phone.
I went to the repair shop today, he said it's a charging port issue on which I have some doubts that why it is even charging in this way if it's a port issue. I just want to make sure if whatever he's saying can be somewhat true.
Can you please help me out? I would be really thankful to you.
I look forward to hearing from you soon!
Thank you!
PS: I tried to search about the port issues but I couldn't find anyone having this kind of issue so please!
The issues you have mentioned really do all point to a faulty USB board......it is common (with a faulty board) for some functionality to work while other functionality is lost. The part itself costs pocket change and is reasonably easy to DIY replace......
If you want to go down that path, check my profile for threads I've started.....you'll find a guide explaining exactly how to do it.
Just make sure to read and note the section on 'rev versions' it is VERY important to get the correct one......

Fast Charging issue

I have noticed that fast Charging does not always happen even with the stock charger. However, if I reboot then fast charging kicks in. Is this a known issue?
No, I always have fast charging. Maybe you need to return your tab for warranty.

I have this problem as a result of getting something in the charging port, or inside the USBC cable itself. All resulting in a moisture detected error. Powering down the tablet, plugging it in and allowing the charge indicator to come on would resolve the issue, but every time I unplug the tablet I would get the error again. I followed instructions on XDA regarding USB C fast charging problems and it seemed to fix the error. I think there's still something in the cable itself because the whole problem has expressed twice now. But in the interim comma over a few days if I plug the charger in one way I would get a slow charge warning that I wasn't using the original charger. But it's the charger that came in the Box. If I unplugged it, turned the charger around and plugged it in the other way it would fast charge again. So I'm guessing there's some kind of material in the charger itself that I can't get to that's affecting how many contacts are being made. I'm still working to resolve the issue with the original charger, but I'm thinking about just getting another USB C cable. I need a longer one than ships with the tablet in the first place.
When I went to chat with customer service, they wanted me to send it in under warranty. But I really didn't want to do without the tablet for 2 weeks or more, so researching it online has solved the issue somewhat. I might take it in to a Samsung kiosk and just see if they'll try to fix it with air duster.
